To all whom it may concern:4

Bo it known that l', CnAnLEs BALLnnion, o'eitize-n oi: the United States, residing at Pueblo, in. the county oi' Pueblo und State of Colorado, have invented certain new :rnd useiul Improvements in Hand lteZor-Stroppers, of which the following is s specification.

My invention relates to n device for sharpening; razor blades, 'and consists of s. device in which n, rotatable cylinder is pported in juxtaposition to e roelii'ig support. for :t razor blade, und ineens wl'ierel'i5Y the letter may be presented. tungontiztlly to the egim: der and held `under stress, and in certain details oii-eonstructioi'i fully set forth herein-v )art section: Fie. 3i e transverse sectional f t? l .'olevstion; and Fig. 4, o. sectional elevation showing o modification.

A freine A ol any suits-ble construction, provided with e handle or holder B, supports the ops gperts. These ports essentially consist one cylinder C, o support D for the. razor blade, end ineens for roteting the cyl inder and rocking the support, and holding the latter so that the blade X is held under stress zigffiinst the. surface of thc cylinder in e, position. shout tangential to the letter. As shown, the eylinder is mounted upon e sha-ft l which extends through the ironie, and is provided with n handle 2O,y and the rotation this shaft is the means of rocking tl z supo' rt l). Preferably, the support is rocked l in one direction and then in the other, so es to present the blade to the cylinder, it one sido and then at the other, the ier being,I rotated any desired number times before reversing` the position of the blade, end the .rotation of the shalt is inode the 'ineens also, in connection with other do vices, oi holding the blade under stress so es f to beer with considerable force against the lisce olf the ej inder.

no shown. he support if) has trunnions 2 to f 't 'ci is secured o grooved pulley 3, sind e tri t on hond i olf any suitable character moundssid pulley ond around the pulny on the shaft i. As o result, umn turning; the oliol't 1, the support 'D isroo .ed

until the binde is brought to beer upon the face of the cylinder, :lifter which the band fl will be carried .by the pulle 5, but will slip oroiind the ,pulley 3 in Contact therewith,

exerting a friction notion, tending to turn the pulley sind holding the blade under stress against the cylinder. 'When the motion of the handle is reversed, the cylinder is turned in the opposite direction und the position of the support D is reversed, and to prevent lany possible cutting of the cylinder when latter is Used as o butler, I provide means whereby tl'ie reversal of the. support takes pince before the eylinder begins to rotate. As shown, this is se-oured by providing the shaft 1 with o lng 6 arranged between two seperated shoulders 7, 8, of the cylinder so that the shaft 1 con turn to a, limited extent in either direction before the lug is carried from one shoulder to the other.

The e linder 'may be a. boiling cylinderprovide with s soit leather facing 9, or it may be a grinding cylinder of any suitable character so es to set as e hone..

To prevent the. cylinder from turning freely on the shaft in changing the direction ot rotation, l provide it with n spjji 14 bearing upon e washer l5, which is carried with the cylinder and bears upon the side of the freine. Y

The support l) is provided with. any suit-- able clamping ineens and is formed accord ing to the chai-noter oi the blade to be clamped. As shown, it is adopted Ato sup port the blade of a Gillette razor, und has two lugs 10, 10 adopted to the recesses oi said blade, and it hinged clamping plete l2 which may be brought down the binde and then secured by o sliding boit 13.

lin Fig. l I have shown the device :is 'provided 'with two cylinders for shznpening both edges oi s double-edged blade, or for simultaneously sluirpening1 two blades. ln thisy cese there .is added fr second cylinder C, and the shaft l carries two pulleys, one et each end, the bond 4 of one ulley` passing to o pulleypn the trunnion ot the support, while ythe bond 17 from the other pulley passes to roclring blade support and ineansvior rocking'the su' port and holding it under stress with the iliade affainst shaft extendin al rotatable to a limited extent in each direction.4 inde endently thereof, andA means whereby tre eylinder is turned .from the shaft in each direeti n after the rocking of the supporh.

The'combination with the cylinder and means for rotating the same in each direction, a rocking su port for a razor blade parallel to the cylindbr, and means for turning the cylinder connected friotionally with the support to rock and holdl the latter under stress'. A

4. The combination with the' rotatable cylinder, shaft and pulley, of a rockingv razor blade support andpulley and driving band passing round loth pulleys, all arran edA to present the blade the cylinder. l

5. rlhe combination with the rotatable cylinder, shaft and pulley, of a rockingrazor blade support and pulley and drivingband passing round both pulleys, all arran ed to present the blade to bear tangentia ly on the cylinder, and meanawhereby the shaft is capable of a limited rotation independently of the cylinder.'

6. The combination in a razor-blade SharpA ener, of a cylinder rotatable in both directions, a rocking support for a blade parallel to said cylinder and adapted to be turned to the, cylinder, of a through the cylinder and to bear tangentia ly on' present either side of the bladegat the edge,

tothe cylinder, and means for rotating tee cylinder and rocking the support to A hold the blade under stress in constant Contact With'said cylinder during the continuous rotation of the cylinder in either direction.

'7. "In a device of the class de scribed, a roL tatable sharpening member, means to rotate it first in one and then in the other direction, a holder for the blade to be sharpened, and mea-ns to automatically reverse the bladeholder at each reversal of rotation of the sharpening member and apply the blade pro erly thereto to be acted upon and sharpene 8. In a device ofthe class described, a rotatable sharpening member, Ineens to rotate it irst in one and then in the other direction, and to stop rotation for a predetermined eriod at eaoh reversal of direction, a holder tor the blade to be sharpened, and means to automatieall each reversa of rotation of the sharpening member during the period the latter is nonrotating, whereby 'the blade is brought into operative *engagement with. the sharpening rember before the rotation oi the latter ie bebun. y
